Question

How to Create a Additional Logical Network adapter in Windows XP / Vista

Asked by: prakash_prk

Dear Experts,

There are two proxy servers in my college. Proxy1 & Proxy2,
Proxy1 -> Linux - Squid
Proxy2 -> Windows 2000 - Wingate (It Also act as DHCP server)

Access Control
Proxy1 allows all the clients.
Proxy2 allow only allow DHCP clients ( dhcp clients allocated by itself )

To use Proxy1, I just change the Internet Explorer Proxy settings to Proxy2.
To use Proxy2, I should configure my machine as DHCP client. After changing that It browses to the internet well

My pc have a static ip address configured. So I can use only the Proxy1.
If I want to use the Proxy2 I should reconfigure my machine as a dhcp client.

I want my pc can use both the proxies without making it as a dhcp client.

Is there anyway we can create additional logical network adapter which binds to that dhcp server.

adding another IP address should be way to go.

@ control panel | network connections | local area connection | general | properties |TCP/IP | General | Adavnced

how to make that another ip is automatically configured from the dhcp server?

 

by: bbaoPosted on 2008-03-19 at 14:57:03ID: 21166302

no, if you use DHCP server, you can't get additional IPs. only one dynamic IP is assigned per PC.

 

by: prakash_prkPosted on 2008-03-23 at 21:51:43ID: 21192001

Ok. Then how to use the proxy on the Proxy2.

I searched come accross a concept of virtual networks adapters(VMWare/Virtual PC).  VMWare/Virtual PC defines additional logical network adapters. The virtual OS's use that adapter to connect to network.

Is that possible we can use the logical n/w adpater in the host machine as another network card to solve the problem (The logical n/w adapter to be configured for dhcp client). ?

 

by: bbaoPosted on 2008-04-22 at 00:45:36ID: 21408796

if you want to use a virtual machine (VM), the IP that it obtains from the DHCP server is for that VM only.

therefore, it is the same thing. only *one* IP per computer. you are using *two* computers here, one IP each.

 

by: prakash_prkPosted on 2008-04-22 at 04:40:40ID: 21409882

I want the virtual n/w adapter in the host machine. I does not want to start a new instance of the VM.

I can easily resolve the problem by adding a two NICs.  But I does not want an another NIC.

> I want the virtual n/w adapter in the host machine. I does not want to start a new instance of the VM.

theoretically, this can be done by using VLAN trunking, but it requires that the network switch, the network adapter, and the drivers for the operating system all support VLAN tagging in order for them to trunk. additionally, each DHCP server should be put in a separate VLAN.

i don't see it is suitable for your particular scenario, if you are looking for a money-saving solution.

FYI: Use VLAN trunking and Gigabit Ethernet for smarter multihoming
